Thisginvention relates to stenographic ma-' chines. Known stenographingmachines leavel irregular spaces often too large between the printedcharacters. In known systems, vseveral syllables are not made on thesame lines; no margins separating the texts for a page. v l i Further,one cannot recommence writing at the beginnin of a line and it is noteasy l0 to read over'w at ,is written.

The present invention has for object to avoid or lessen theseinconveniences and to provide a stenographing machine in which chieflythe impression of the characters one after another takes place withoutirregular spacing there-between, as well as the impression of severalsylables on the same line in which the production of a margin is madewhen a surface of the predetermined size is printed. It offers, also,the possibility of instantaneously replacing the machine in position torecommence theV impression of a" complete page or of a new line, even ifthe preceding work stop d at the middle of a 25.page or at the midd e ofa line; there will also be found means for causing the printed paper toreturn to its starting position with-.- out necessity of withdrawing the.enrolling cylinder from its norinal position. d "Finally the means forrolling up the paper as printed, to enable it toy be read is efected bya inig'er on the handle of a sector, thus causing t e abru t enrollmentof several lines at once. t also offers various l other advantageswhchwill be obvious from the description hereinafter given.

The invention will now be described in detail by reference to theaccompan ing drawings 'showin by way of examp e and dimagrammatica y, avform of construction ol' a stenographing machine for writing onseparatesheets or on rolls Aof paper.

Fig. 6 is a front elevation of partfof the guide frame for the keylevers.

i Figs. 7-8-9-10 indicate details of construction.

The machine forming the object of the invention, stenographs in ordinarycharacters and permits of writinwith a single touch,

- av complete syllable w ich may have anyp thing up to six characters.

The keyboard of the machine enerally has twenty-six keys; at the lefts1de there are ten forthe consonants or combinations of consonantscommencing the syllable; at the centre there are six"`for the vowels.I-A- E--O- U-lI which may be touched alone or preceded by'or followed byone or several consonants; at the right side, ten for the consonants orcombinations of consonants terminating the syllable.

This arrangement of the characters or keys permits of writing at asinvle'touch by the-simultaneous depression of t e necess y keys, sixcharacters in the order in whic these are placed in the syllable.`

The order in which the characters follow each other on the keyboard isestablished in conformity with the result of a p hilologic n the Laan 1ms study of'steno la hy.

VIn the parti` ar case of guage, in general certain consonants occupyanunchangeable row before the vowels, 'in relation to other consonants,for example never precedes S, at the commencement of a syllable; N neverbefore M, L never before .I

M, etc.

The board is as follows:

. From left to right initial consonants:

U'I-nthe centre, the vowels; I-L-E-O- i At' N-L-Mf-GK--VF-BP-J-Sf-TD.

As will be seen, the consonants having `about the same consonance arejoined into order of the characterson the keythe right, the terminalconsonants;

a single one, it is thus that when impressed, A'

D or T- are Tidered by DT; -B and Plliy BP; V and by VF; G and K by G;this is for the purpose of reducing thevnum-A ber of keys.

There are twenty-six characters distributed over the periphery ofthirty-six sectors 19, which form in the machine six grou of sixvsectors each; the sectors bear in re 'ef the following characters;

First sector left side; S-DT-Bl--GK- VF. Second VE-L-M-R-N.

Third sector; SDT-BP VF-L -M-R-'N--L Fourth sector; Af-E-O-U-R-N-Ir-M-GK-'VFL-BP-J-S-DT Fifth sector; E-O--Uf-I-R-N-L-- M-GK-VF-BP-'-J-S-DT.

Sixth sector; .I-R--N-:L-M-KGK- VF--BP-'JS-DT.

Each key 1 is integral witha lever 2'piv- Oted on a axis 3. Each keythrough the intermediary of its lever 2 and of a tension ,member 4pivoting at 5 acts on a cam 11 turning'around'an axis-14.I

In 'depressing ai key 1a downward' movement is given to the tensionmember 4 which latter by reason of its roller 6 pivotingon 7, transmitsand transforms the movement of the cam into ajpartial rotary movement.

. Each of the cams 11 can control three intermediate wheels 15. In theposition of rest, theycams depending from the nine iirst "keys on theleft side come beneath the third intermediate wheel,- the cam of thetenth key N .comes beneath the second wheel and the .cam controlled byinitial I comes beneath the singlewheel which it. controls.

The cams depending from the ve other' vowel keys as well as thosecontrolled by the keys of Lthe terminal consonantsare laced, in theposition, of rest, beneath the rst of the three intermediate wheelswhich face them. v

.The `intermediate wheels carry on their contours an isolated tooth 151,by means' of a trolled by the eleven initial keys can act equally upon4the sectors, they are reproduced beneath these, which permits of'theeleven. left hand keys to influence the three rst secv tors of eachofthe six groups and thus to print vthe initial consonants and the firstvowel I. By following the mechanism it will be, seen that 2O is the axisfor the sectors 19;

21 is the roller' compressingthe paper ly thesi-x groups of sectors inposition for impression.

On the axis 2 611is found a double tooth segment which at each' halflturn corresponding to the impression of a lin'eof six syllables, causesthe ratchet 291 to advance one tooth and by means of the toothed sector30, the pinion 32 of the enrolling member 37 to the value of one line.

c On the axis 2611 is also mounted the wheel 27 which at each lift ofthestirrup imparts to the axis carrying the stds a sixth of a turn.

281-2811 are springs for returning the stirru'p, the`key levers and theframe 2111, the wheel 29 and the ratchet are integral and receivetheirmQvementfrom the stirrup and the double segment 26 and istransmitted through the sector 30 to the`wheel 32 andthe enrolling-member 37;

The sector 30 can be'operated by, hand by t e handle lever 33 and theenrolling member rule 18 lixed on/a bridge 17having a return V,h

4spring 171 and introduced in the teeth ofv f each Wheel of the samegroup, so rendering' these Wheels integral onewith another. It followsthat upon the depression of a key and the rotation of its cam one of thethird is made to turn and all the third wheels controlled by the nine kesin question will turn at the same time wit out the need of their keysbeing depressed.

In short, thev operation of one key of any description in the -rightgroup or' the left hand group arranged at -no matter what part of thekeyboard transmits Vits 4movement to all the wheels of the same value;these being integral the ones with the others.

' Each .of the intermediate wheels placed opposite the cams of the keysA-E-O- U-I-R- can mesh with a character impression sector 19.

In order that the intermediate'wheels conwheelsof the` nine first' keys,for example.,

page by the button 2911.

.The cylinder 34 is a housing for blank. paper and 341 are buttons `forturning it-by hand. 251, 261, 271, 4321, .391 are drums lon which-are.wound tension springs vfor the tension members and brakes. Pinion38.01?

can be replaced at the commencement 'of a the enrolling member mesheswith wheel 39 on'the axis 391I carrying the brake ,39111 and the handle401, the brakes opposing the back- 'ward movement ofthe enrollingcylinder while. the disengagement by means .of the handle 401 permits ofthis backward movenient.v Y'

A spring 54 causes the automatic contact between the lball 'race 541 andthe pivots 371 of the enrolling shaft 37; the looseningv oi the screws55 andthe pulling of the knob 551 frees the enrolling cylinder;

Beneath the key leversand entire width of the machine, is'a 23traversing the l 23 acts upon the gear 26, 27, 29 on the small toothedsector 30 as Well as on the pinion 32 of the enrolling cylinder 37 andon the pinions 27 and 52 thuscausing the enrolling or advance of thepaper when a line is printed and the successive impression of the sixsyllables by theimpressing mechanism is made.

The stirrup has the further function of acting upon the frame whichcarries the caoutchouc roller over which passes the paper and tocompress the latter against the sectors to obtain the impression.

If it is now desired to Write with. the machine and print for examplethe Word of a single syllable Soupe the keys bearing the characters tobe reproduced are simultane ously depressed; stenography being phonetic,one does not Write soupe but soup (e) one depresses therefore initial s,at'the left side, at the right, these four keys will therefore cause apartial rotary movement to the four cams 11 which they control.

The cam for initial S, in turning, will act below the intermediate wheel15 which is opposite to it, that is to say the third, and this onecarrying along with it, through the striker 18 of the bridge 17 theother wheels placed beneath the eleven left hand keys, as well as thethird Wheels placed beneath the sectors, will lift the' third sectors ofeach of the six groups until the letter S comes in the axis of theimpression roller.'

To write the letter ()-U-BP the keys bearing these charactersaredepressed.

In depressing the lirst of these keys, one imparts not only a partialslrotation of its cam but the latter d1splaces`laterally from lefttowards the right all its neighbours (from 1.5 mm. i. e. the thicknessof one intermediate Wheel). This displacement is obtained in thefollowing manner: Each cam is furnished on one of its bases, on the leftfor the left hand grou ,f at the right for those of the. right hanrecesses in the form of a V. 1

These recesses receive in the position of rest the protruding part of1.5 mm. of three steel balls 4-1 placed in the housings 43 formed on theintermediate members having three arms 41.

In turning, each cam, by the action of its V-shaped recesses on theballs, forces these to spread apart to give it passage.

Fig. 10 shows an element of the cams of the right hand group during theaction of the key lever of the cam 11.

Any displacement in the opposite direction i. e.y towards the centre ofthe machine is made impossible for the cams of both groups by thepresence of the d1vision45l.

o 'ze in themiddle and BP terminals group with three i It. thereforeresults that eac-h time a cam is made to turn its neighbours aredisplaced, to the left or to the right, by the thickness of oneintermediate whcel. p

It is thus that having depressed the key O and caused its cam to turn,it will act on the irst intermediate wheel, one will obtain by lateraldisplacement to the right change of position of the other cam which itis desired to rotate; they will now act on the second intermedi-atewheel and influence the itth sector while the cam will act upon the.fourth sector. In nextlt'm-'ering the key U, the same lateral movementwill occur for all the neighbouring keys to the right of U including BP,towards the right in such a manner that t-he final result is obtained asfollows; S not displayed laterally, or willv act upon the third sector;O not displaced laterally, will act upon the fourth sector; U displacedby-O, will act upon the fifth sector, and BP displaced by 4U, will actupon the sixth sector.

The intermediate wheels must not be influenced, by t-he'cams except whenthe lateral` movement thereof has ceased.

For this purpose the shaft 14 of the cams is not in contact with theintermediate' wheel, but between the two members is reserved suiiicientplay to permit of the necessary rotation of the cam for the spreadingapart of its neighbours.

, The characters of necessity occupy each another place on the peripheryof the sectors; it results that the cams must give them a shorter orlonger stroke according to Whether the character is placed at thecommencement or at the end o-f the arc of the sector.

For example initial S placed at the top of .the sector, wouldnecessitate a less depression of the key than initial R at the bottom.

Nevertheless, the stroke of each key lever must be of the sameamplitude. To conciliate these two conditions use. has been made of thespecial tension members 4. These carry at the upper half of their lengtha` member furnished with an inclined plane 10.

This member is mounted at a variable height for each tension member, insuch a manner that when the character to be imf pressed has reached theaxis of the impression roller, the member 10 by its descending movementimparted to it by the lever 2, abuts against the stem 9 which passesthrough the whole width of the machine.

The tension member, although the key lever alwasescends, still followsbut no longer acts on the arm 12 of the cam 11.

In fact the inclined plane causes the teusionl member to commente amovement around its axis, backwardly, und .this movement which has nofurther ell`cct upon the cam lasts as long as the. lever2 does not,commencev its upstroke. At this moment the return spring obliges thetension member to return to its initial position.

The key levers 2 no longer having any action on the sec-tors,intermediate wheelsv and cams, as soon as the required character 1spositioned for printing, the rest of their stroke is utilized to provokethe contact ofv the rubber roller 21 which carries the aper with theraised sectors to form the sy lable and thus produce the impression.

T-he roller 21 is mounted on the upper part of a frame Whose lower crossmember passes'below the stirrup 23 at a distance such that the lattercomes in contact with that one shortly before'the end of the movement ofthe stirrup.

By this contact the roller 21 is displaced towards the axis of thesectors, presses the pape;` against the characters which have becomeinked in passing on the inkingl roller 22 and causes their impressionupon ythe paper.

It has been seen above that the interme diate Wheels of the same groupshaving beenv rendered integral one with the other by the bridge 17 andits striker 18, each time that af wheel is set 1n motion, all thecorrespond-l ing sectors of the six prlnting.

Nevertheless it will be seen that the sectors rise on'e after another,firstly those of the first group, then those of the second group, fthethird group etc. up to the sixth group,

groups were raised for because this successive movement alone gives theimpression of the six consecutive syllables, upon one line.

To ensure that the six groupsact one after another an arrangement hasbeen adopted consisting of the shaft 52 furnished with a pinion 52I andsix studs 53.

This shaft receives its intermittent circular movement through theintermediary of the wheel 27 each time the connecting rod 25 returns toits point of departure, it causes the shaft 52 to turn one sixth of aturn and places successively each of the group yof the sectors inposition to gear with intermediate wheels. v 4 i The six studs mountedon this shaft also comes successively in contact with the faces of agroup of sectors, causing the raising of the group and obliging it thusto mesh with intermediate wheels to be subjected to their influence.

When it is desired to place the machine in position to start a line i.e. to impress the .first syllable of a line, the first stud 53 is placedin contact with the first group of sectors, by the number of depressionsnecessary on a punctuation or space key 35, 36.

The large Wheel 29 which receives its movement through the connectingrod 25 is integral with a ratchet having 47 teeth. A pin 31 of thesectors 30 rests at the bottom of 'reason of the rotation of the ratcone of the teeth of the ratchet 29I and when 65 at each of its movementsthe rod .25 imparts an intermittent rotary movement ,to the wheel 29 andto its ratchet, the in 3 1 by liet leaves thel bottom of the tooth,passes above the top thereof and lodges itself in the neighboring tooth.

This movement is accompanied by'that of the sector 30 to which the pin31 is fixed and isfinally'transmitted by the pinion 32 to the lenrollingcylinder 37; the advance` of one ratchet tooth is translated by anadvance of 5 mm. length of paper; this constitutes the interlinin Anarrangement permits of printing 4surfaces of commercial size and toreserve between two printed sheets of this size a blank margin of such aWidth that itbwill be easy v to divide the rollers printed in sheets ofequal size and classify the same.

The ratchet with its 47 teeth; Ithe space occupied by one of its .teethcorresponding to the value of one line, one will have printed 47 linesto each turn of the ratchet wheel.

These 47 lines form a page; the447th tooth of the ratchet having ahollowspace deeper than the others permits the pin 31 a greater drop andconsequently gives to 4the sector 30 more movement yet imparts greatermovement to the enrolling cylinder 37, so pro-l viding a blank margin.

When, before starting the work on the machine it is desired to place itin position to start a full page, the knob fixed at the end of the pivotof the wheel 29 and of the ratchet, is turned in such a manner that thepin 58 bears upon the pawl 57 which itself rests upon the stop 59.

This position of the knob and ratchet which itcontrols, coincide withthe commencementof a page.

The frame 46-48 with its supports 47 is destined to guide the keylevers; the upper bar 46 can be removed for the introduction of thelevers in the frame.

When ther action on the keys has ceased the different organs return totheir initial positions with the exception of those which have to havean action intermittently but in the same direction.

The key vlevers'are brought back by springs 28I the cams turningbackwardly and the intermediate Wheels returning to their places throughthe action .of the springs acting upon the ridges and strikers 17 and18, the sectors redescend under the action of the intermediate Wheelsand by their counter- Welghts, the stirrup 23 rises again, also byreason of the spring 28; the laterally displaced cams are returned totheir initial positions by two plates 45 disposed at each extremity ofthe axis carrying the cams and influenced by an antagonistic spring 45.

The paper housed on the cylinder 34 passes between the roller 21 and thecounter roller 21I and after having passed around the roller 21 rollsitself upon the cylinder 37.

The members destined to have no movement backwardly are held in positionby brakes consisting of tension springs; the members, under theinfluence of said brakes, can freely turn in the direction in whichmovement is allowed them, but the tension of the spring preventsmovement in an opposite direction. In the machine lthe brakes areapplied to the following members:

1. In the pinion 32 in which the ascending movement alone of the sectorhas to be imparted and not its downward movement.

2. On the drums of the movable members carried along by the connectingrod and controlling the large wheel 29 and the pinion of the axis 52.

3. In the brake 39, this brake which prevents the backward movement ofthe cylinder 37 is mounted against the right rear bed-plate on an armpivoting and constituted by a wheel 39 to which a spring brake 391, intension, permits of a' movement in one direction only.

This wheel meshesl with a pinion 38 mounted on the enrolling cylinderand when these two movable members mesh together the return movement ofthe cylinder becomes impossible, but when for the purpose of re-reading,it is desired to turn back the enrolling c linder in the oppositedirection to unroll t e paper, the arm 40 is pushed back with the wheel39 out of gear so that the cylinder is freed and can turn in bothdirections.

When, for the purpose of re-reading, the paper has been caused to turnbackwardly to the start of the printing, in order to wind it back stepby step as the matter is re-read, the handle lever' 33 mounted on thesector 30- can be used. The action of the finger on this handle permitsof enrolling the portion of the sheet which is visible and which hasalready been read through, by a single and rapid movement.

The two keys 35 and 36 are articulated and provided with a returnspring, each on a lever which acts when it is depressed, on the stirrup23; they impart, the first a sixth of a turn, the second, two sixths ofa turn to the shaft 52 with its studs 53.

That causes one or two spaces of the width of one syllable on the paperand acts as punctuation; the key 35, one blank syllable, equal comma;the key 36, two syllablcs blank equal full-stop.

The mechanism constituted by the laterally displaceable `cams foroperating several groups of sectors and thus give the impres sion ofseveral syllables on a same line as in the constructional embodimentshown, or else act on a single group of sectors; in this latter case thepaper is displaced in the opposite direction and the impression is madeon a narrow strip, the syllables follow each other continuously on thesame This arrangement would be advantageous for machine writing on anarrow ribbon lengthwise and continuously from left to right.

In the drawing is shown a machine impressing six syllables but thisnumber is not limited and the number of syllables can be increased byincreasing th'e number of groups of sectors.

The same applies to the keyboard in which the number of keys may vary,the keys 35 and 36 can be'operated by the fingers but their dispositionenables them to be actuated by the handles so that the fingers do nothave to leave the keys.

Having now particularly described and ascertained the `nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:-

1. A stenographing machine having character bearing sectors, meansincluding cams for operating said sectors, and means operative in themovement of one cam to induce lateral movements to adjacent cams forsubsequent cooperation with other sectors.

2. A stenographing machine having character bearing sectors, meansincluding cams for operating said sectors, means operative in themovement of one cam to induce lateral movements to adjacent cams forsubsequent cooperation with other sectors, and tension members to causethe cams to move through a predetermined angle.
